This is a tough one, there are many variables involved, I had a Rabbit that
did the exact same thing.  I had tried everything and came to the conclusion
that it's fuel pressure related.  Never solved it completely, I sold the
Rabbit, but here are a couple of quick fixes:
Check your plugs if they are black or dark brown you can lean out the fuel
mixture.  This will decrease the severity of the problem.  Also it will make
your car a lot more fuel efficient.  If you don't want to mess around with
that:
When the engine is warm or hot unplug the fifth injector electrical
connection and try starting it at various temps.. If that helps then you
need to put in a switch between any of the two wires that are connected to
the fifth injector and have it on the inside of the car.  So when it's warm
or hot the fifth injector can be off, and when you start the car cold you
can have it on.
The fifth injector squirts fuel at all temp. ranges for varying periods of
time.  I think from 1 to 3 seconds.  DO NOT completely leave it unplugged,
if it's cold outside your car will not start or start really hard, without
the extra fuel.
